Calendar data is often locked in .ics files, making it hard to analyze or manipulate. Converting ICS to CSV allows you to open your schedule in Excel or Google Sheets, enabling you to track time, analyze appointments, or prepare reports with ease.
What is ICS to CSV Conversion?
ICS (iCalendar) is a universal calendar format used by almost all scheduling software. Converting it to CSV flattens the complex event details (like start/end times, descriptions, and recurring rules) into clear rows and columns that any spreadsheet application can read.
